ZF 0730.162.349 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.162.349 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG 200 Series transmission family. This critical shim element sits between the planetary gear set and the clutch housing assembly, maintaining exact axial clearance to ensure proper gear engagement and oil flow distribution. The SKU 0730.162.349 functions as a load-bearing separator that prevents metal-on-metal contact between rotating assemblies, directly influencing torque transfer efficiency. When installed alongside the 4460165051: CONSOLE and the 4460368311: CONSOLE, this spacer ring completes the structural foundation for the WG200’s main drive shaft alignment.

Symptoms of Failure

• Gradual transmission oil seepage at the bell housing joint — When the spacer ring wears unevenly, it creates micro-gaps that allow ATF to escape past the seal interface, often mistaken for a simple gasket failure.
• Intermittent gear slipping under moderate load — A degraded 0730.162.349 reduces clutch pack clamping force, causing hesitation during 2nd-to-3rd gear upshifts in WG200-equipped vehicles.
• Metallic grinding noise during cold starts — Worn spacer ring material allows the planetary carrier to contact the housing, producing a distinct scraping sound that disappears as the transmission warms up.
• Increased axial play at the output shaft flange — Measurable end-float beyond 0.15mm indicates the spacer ring has compressed beyond its service limit, requiring immediate replacement.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG200 series transmissions, including the WG180, WG200, and WG210 variants used in medium-duty commercial vehicles, construction equipment, and agricultural machinery. It directly replaces the original factory-installed ring in all WG200 gearboxes produced after 2008. The part also cross-references with certain Voith DIWA.3 applications that share the ZF planetary carrier architecture. For proper installation, always pair this ring with a new 0636011429: HEXAGON SCREW and 0730100365: WASHER to maintain correct torque specifications.
